The Hurel-Dubois HD.10 was a French research aircraft first flown in 1948 to investigate Maurice Hurel’s ideas about high aspect ratio wings. It was a single-seat monoplane with retractable tricycle undercarriage and twin tails featuring an extremely long slender wing with an aspect ratio of 30. This was mounted above the aircraft’s enclosed cockpit and braced with struts. Construction was of metal throughout.
